Phi Gamma Delta's biggest secret is its handshake. Other secrets are not widely known because members never leak the information. It is suggested that Phi Gamma Delta and other fraternities are gateways to freemasonry and the Illuminati, and that fraternity rituals mirror those of Freemasons.
To learn Phi Gamma Delta's secrets, a college student must pledge and be initiated. Once initiated, the student learns the secrets, from rituals to meanings behind symbols, colors or creed. Though many were begun as secret societies, fraternities like Phi Gamma Delta have become more transparent as the years have progressed, more schools have added chapters, and more brothers have been initiated.
